Avid Studio for iPad arrived back in February, priced to coax iPad filmmakers away from Apple's in-house iMovie. Since then, however, the company sold its consumer business arm to Corel, leading it to re-brand the package as Pinnacle Studio for iPad. The editing app has gained a bunch of features that users were clamoring for, including 1080p support, integrated uploads to Box and a raft of stability tweaks. As part of the change, it's being offered free for a limited time, so if you own an iPad (or plan on getting one in the future), we suggest you jump-cut to the App Store pretty quickly.
